can anybody help me

[kewlbear]

You should change DEPLOYMENT_TARGET to 8.0 or above. If you are trying to build FFmpeg 4.0, see DeviLeo/DLGPlayer#19 and http://ffmpeg.org/pipermail/ffmpeg-devel/2018-April/229129.html.

[Ahmedbutt]

I have removed followng line:

• _swri_oldapi_conv_flt_to_s16_neon:
• _swri_oldapi_conv_fltp_to_s16_2ch_neon:

But I am still getting following issue.
clang: warning: optimization flag '-fomit-frame-pointer' is not supported for target 'armv7' [-Wignored-optimization-argument]
:61:1: error: invalid symbol redefinition
_swri_oldapi_conv_flt_to_s16_neon:

@kewlbear

[kewlbear]

There are two more modifications needed besides removing those two lines.

[Ahmedbutt]

I ave done following change:
Delete _swri_oldapi_conv_flt_to_s16_neon: and _swri_oldapi_conv_fltp_to_s16_2ch_neon:.
Change _swri_oldapi_conv_flt_to_s16_neon to X(swri_oldapi_conv_flt_to_s16_neon) and _swri_oldapi_conv_fltp_to_s16_2ch_neon to X(swri_oldapi_conv_fltp_to_s16_2ch_neon).

But error still persist...

@kewlbear

[kewlbear]

I confirm that http://ffmpeg.org/pipermail/ffmpeg-devel/2018-April/229129.html works. The other one doesn't work.

[Ahmedbutt]

Can you see content of libswresample/arm/audio_convert_neon.S? What I am missing?
